Question

Q13. Find the value of k, if (x - 1) is a factor of 4x³ + 3x² - 4x + k.​

Answer 1

Answer:

k = 3

Step-by-step explanation:

Because x-1 is a factor of polynomial, so x=1

Putting value of x in equation/polynomial-

4x³ + 3x² - 4x + k = 0

4(1)³ + 3(1)² - 4(1) + k = 0

4 + 3 - 4 + k = 0

7 - 4 + k = 0

-3 + k = 0

k = 3

Answer 2

Answer:

K= -3

Step-by-step explanation:

X-1

X=1

4x³ + 3x² - 4x + k.=0

4+3-4+k=0

K = -3
